Intelligent panel system

An optical system comprising:

• a first optical receiving device located in a first optical fiber and termination assembly and control unit, the first optical receiving device configured for receiving and detecting second optical signals;
• a first optical filter located in the first optical fiber and termination assembly and control unit, the first optical filter configured for optical communication with the first optical receiving device;
• a first optical transmission device located in a second optical fiber and termination assembly and control unit, configured for optical communication with the first optical receiving device via a path comprising an optical fiber extending between the first optical fiber and termination assembly and control unit and the second optical fiber and termination assembly and control unit, and configured for causing the generation of the second optical signals;
• and
• a first central processing and transmission unit in electrical communication with the first optical receiving device, the first central processing and transmission unit being configured for transmitting radio or electrical signals carrying data based on the second optical signals and specifying at least one of a value indicative of an optical path length for the optical fiber, a value indicative of an optical dispersion for the optical fiber, or a value indicative of an optical latency for the optical fiber,
• wherein the second optical signals have a second wavelength, are transmitted from the second optical fiber and termination assembly and control unit to the first optical fiber and termination assembly and control unit, and are distinct from first optical signals that are conveyed from the second optical fiber and termination assembly and control unit to the first optical fiber and termination assembly and control unit, the first optical signals having a first wavelength different from the second wavelength such that the second wavelength provides a dark channel by which the second optical signals are routed from the first optical filter to the first optical receiving device without the first optical signals being routed from the first optical filter to the first optical receiving device.
